(The author wrote this for fun. It was inspired by a rage after eating a stone in other pre-Civilization fanfiction. And although this book is a pre-Civilization fanfiction, there is no yuri, no yuri, no yuri. The author himself hates yuri!)

A paranoid and arrogant time traveler, guided by a higher-dimensional will (the author), embarks on a journey to save the world in order to return home. He hates the tone of this world and everything in it, and scoffs at the idea that love can save everything. However, in order to return home and save the world, he is willing to give everything he has.

Maybe it's a multi-heroine romance? Probably. I wrote it with a magic tool, so don't expect it to be too logical.

Alicia: "Oh, Xiaochen, you are so cute. This pink skirt must suit you very well! Oh, don't run~"

Mei Lei: "Su Chen, I am willing to fall into darkness in exchange for you returning to the light, just like you once saved me."

Xilin: "Brother, you said you would stay with me forever. This time I won't let you leave my side again."

Lin Zhaoyu: "Big Brother, do you remember that you still owe me a promise? I am willing to spend my life with you."

The Herrster of Knowledge: "Traitor, come and take my sword!"

How do you redeem someone? Answer: Bring her home, care for her meticulously, and treat her well without asking for anything in return. After she becomes completely dependent on you, have someone dump your body in front of her. Are you here to support the boss? ...PS: A bit slow to warm up

[Multiple Female Protagonists] [Simulation] [Twelve Talismans] [No Sword]

How many evil deeds does a person have to commit?

Only then can I bring her back to the dawn at the end of hell

How far does a person have to go?

Only then can we find our original self at the end of time.

How much can one pay for the love of one's life?

He experienced a magnificent and wonderful journey, met like-minded allies, joined a train, became the third largest shareholder of a company, led the early prosperous forces, and protected the [Cangcheng] Immortal Boat...

Finally, he stopped in Luofu, adopted a barbarian baby girl, and opened a small teahouse - [Floating Cha].

"Dad, are you making up stories again?"

"Oh, stop chanting and go warm the tea for the guests."

"oh."

"One more thing...don't advertise my existence casually."

At that time, Yun Mo was in his prime, talented in both literature and martial arts, and very handsome.

Louis Fleming: Cloud, you are so young~

Marshal Hua: Perhaps, time will prove you right, but I can't prove it now, Junior Brother.

Gopher: I tried to find a way out for my family. I would be happy if you could lead them. I once made a mistake.

On that day, the gods fought a war. Twelve thrones gathered together, gathering the will of all, determined to find a way out for mankind.

This is the wish of all living beings.

Little fox, I found you...

Lin Lanjian traveled to the Collapse Iron World, binding to a system and gaining the power of gods and demons with a single thought! With unparalleled combat prowess, he traversed the universe with a single sword, leaving behind countless legends. "You... are the meaning of life I seek..." The firefly girl, Liuying, whispered dreamily, watching the receding figure, warm as the sun. "I will search for you, no matter how far or how long," the knife-wielding girl, Huangquan, held a red paper umbrella to shield herself from the falling thunderstorm, her murmurs calmly and firmly. ...Swordsman of the Interstellar Peace Company, partner of the Black Tower and Ruan Mei, unknown guest of the Starry Sky Train, Sunday's brother-in-law... Lin Lanjian, with his countless identities, had a fleeting thought of beautiful women. "Which wife should I spend time with today?" he couldn't help but worry.

[2.3 million words completed] Mingyu, possessing the power to rewind time and traveling through a world of collapse, embarks on a journey of endless reincarnation and salvation. "After entering Saint Freya, you made many trustworthy friends." "You attempted to save many girls who should have died young, and in return, received their gifts." "A Certain Scientific Railgun, Mokopotmo, Infinite Space..." "Facing Kevin, you began to chant, summoning a barrier constructed entirely of the Holy Judge of Heavenly Fire." "Facing Alicia, you promised her that humanity would defeat the collapse, but without sacrificing everything." "Facing the Cocoon of the End, you gradually understood everything about that man. You knew you could defeat it, but it would be a long process, lasting eternity." "Traveling through the endless future, you finally transformed this imperfect world into a place of hope."

After waking up, Lin Jiuan found himself traveling through time and space and became the sixth beast of Type-Moon.

In order to avoid the outcome of carelessly eating his own mother, Lin Jiuan cut off his connection with the underground Holy Grail and fled to Fuyuki overnight.

Although there was no mana supply, it didn't matter. As the sixth beast, Lin Jiuan converted his power into the system. As long as he could make those heroic spirits fall, he could get system rewards. From the time he was adopted by the Tosaka family, it was his turn to show his skills...

Rin? Sakura? Why are you two little brats looking at me in a weird way?

Orange, Altria, how come you guys with thick eyebrows and big eyes are so perverted?

No, Irisviel, Brunhilde, be reserved, you have families, right? !

What the hell is it about snatching my custody?

Meili: "Hehe, little guy, you don't want Ai Ge to know that you are surrounded by women here, right?"

Lin Jiuan: "???"

"You bad women stay away from me!!!"

"Playful Type-Moon" is a gal game with a high degree of freedom. Players can unlock new CGs by improving the favorability of the heroines.

After three days of staying up late, Alvin finally successfully unlocked all the CGs and maxed out the favorability of all the heroines.

The bad news is: the favorability is full to the point of overflowing.

But fortunately, it's just a game, so it doesn't matter even if it overflows... Originally, that was the idea, but -

Alvin never expected that he would travel to the game world by chance, and meet Altria, Morgan le Fay, Tiamat, Scathach, Sajo Aika and other Type-Moon heroines in accidents again and again...

When Alvin noticed those pairs of extremely gentle and dangerous eyes, his eyes gradually lost their spirit and he regretted it.

"So... why did I increase the favorability to overflow in the first place?"

Lin En, seemingly an ordinary Chinese language teacher at Sobu High School, harbors a secret. He's the sole occupant of the "Ten Thousand Worlds Safe House"! His "classroom" connects the world's most elite "problematic beauties"! At the outset, the safe house "picks up" a young girl who's recently lost her sister and is filled with hatred. Faced with her murderous intent, Lin En gives her a single assignment: "Go back and face your anger!" As Shinobu Kocho unleashes bloodshed across the Demon Slayer world with this "assignment," Lin En uses his first reward, "Emotion Perception," to precisely tap into Yukino Yukinoshita's loneliness! → Homura Akemi: From "Desperate Girl of Reincarnation" to "Demon God Who Controls Time and Causation," rewriting fate and subverting the universe! → Misaka Mikoto: From "Sinful Princess of Electricity" to "Thunder Empress on the Path to Absolute Power," piercing the divine realm with lightning and reshaping the order of Academy City! Of course, there's also the occasional everyday pretty girl... This world is truly wonderful, but sometimes it's just too much...

It was not until they sorted out Xia Ze's memories bit by bit that they finally understood how many ups and downs, love and hate, separations and partings he had experienced in his life...
